A 76-year-old woman admitted for brown urine was found in blood tests to have hyperbilirubinemia and in computed tomography (CT) to have a mass at the common bile duct and a dilated intrahepatic bile duct and common bile duct. Endoscopic retrograde cholangiopancreatography showed middle common bile duct stenosis. Serum CEA was 7.4 ng/ml and CA19-9 was 40.9 U/ml. Obstructive jaundice was relieved by Endoscopic nasobiliary drainage, but cytodiagnosis was negative. We conducted choledochectomy, cholecystectomy, and choledochojejunostomy bases on a diagnosis of stromal tumor of the common bile duct. Histopathologically, the definitive diagnosis was extraskeletal giant cell tumor of the extrahepatic bile duct, which is extremely rare.
